PAPER-ROLL onnnLn.

Specification of Letters Patent. Patented J 11116 29, 1915.

Application filed December 10, 1910. Serial No. 596,586.

To all whom it may concern:

Be it known that I, HARRY S. McCon- MACK, a citizen of the United States, residing in New Rochelle, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Paper-Roll Cradles, of which the following is a specification.

This invention relates to means for supporting paper Webs or rolls from which the paper is led to the platen of a typewriting machine, and it constitutes an improvement on a portion of the invention disclosed in United States Letters Patent No. 953,854, granted to me April 5, 1910.

One obj ect of this invention is to simplify and improve paper roll holding devices by providing a separate support for each roll, the support and roll constituting a unit which may be applied to or removed from the machine irrespective of other similar units.

Another object of this invention is to enable the use of webs of various widths and diameters with the same paper web support or cradle. This is accomplished by making the roll-supporting cradles adjustable both as to length and as to breadth, the ends of said cradles being connected by rods adj ustable in length and mounted in extensible 7 arms secured to the ends to accommodate rolls of different diameters. By means of this arrangement also, machines may be fitted with cradles of a size designed to support rolls of the particular size or sizes used by the customer, thereby eliminating the necessity for making cradles of varying sizes or keeping a large stock of cradles on-hand. The cradles may be provided for endwise extension without being adjustable widthwise, and vice versa.

Other objects and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a rear perspective, showing the paper roll cradles, the webs being led therefrom over the guides and around the platen of an Underwood writing machine. Fig. 2 is a plan of a pair of cradles, the one on the right being extended to accommodate a roll thicker in diameter than the one shown at the left. Fig. 3 is an end view showing the manner of adjusting the cradle to rolls of difierent diameters. Fig. 4 is a side view, showing the manner of attaching the cradles to the machine. Fig. 5 is a section through a paper roll. Fig. 6 is a detail showing a sectional connecting rod of the cradle,-disassembled with, the cradle standards.

A carriage 1 travels back and forth on a main frame 2, having legs 3 to which feet 4 are secured by screws 5. The carriage supports a platen frame including a paper shelf 6, in which is mounted a platen 7.

Horizontal rolls or webs of paper 8, 9 and 10 are located in rear of the machine with their axes extending rearwardly at right angles to the platen. From these rolls, the webs 11, 12 and 13 are led upwardly to the left (in Fig. 1) to a horizontal rearwardly extending guide bar 14 fixed to the carriage 1, parallel with the rolls.

The webs turn around over the top of said guide bar 14 and thence run to a second horizontal guide 15 extending at an angle of about 45 degrees to the guide bar 14, the apex of the angle being at the rear ends of said guides. The webs dip beneath the guide 15 and fold over the same, whereby their direction of travel is changed to run at right angles to the direction in which they are led from the rolls. Thence the webs are led under the platen 7. Certain of the rolls, as roll 9, may consist of carbon paper to make copies on web 13 of the original writing on web 11, or all of such rolls may be record rolls and the writing on the original web be copied on the remaining webs in some other manner.

The web controlling guides 14, 15 are preferably formed of a single length of wire bent at 14 to give the required angle, their forward ends being secured to collars 15 adjustably secured by set screws 1 on a rod 1 connected to the carriage 1.

The webs are unwound from the rolls 8, 9 and 10 during the return of the carriage 1 to begin a new line, the webs hanging loosely from the bar 14 during the writing of a line to eliminate drag on the carriage.

To enable the operator to maintain a compact device with no unnecessary parts, as when less than the full number of rolls are employed; and to adjust the rolls relatively to the limits of travel of the platen to reduce the length of slack web, each roll is mounted in a separate cradle detachably connected to the machine. Each cradle preferably comprises a pair of ends or standards 16 having feet 1'! resting on a table or support 18 and connected by rods 19 extending about parallel with each other between the opposite ends of the standards. The axles 20 of said rolls fit in bearings 21 formed intermediate the ends of each standard. The cradle may be releasably connected to a bar or support 22 extending about parallel with the platen,

and connected to the main frame 2 by the screws 5 passing through arms 24 on the bar. The cradles may have one or more hooks 23 carried by one of the standards 16 to catch over said bar at any part of its length, to hold the cradle and roll against accidental displacement due to the pull on the roll when the carriage is returned to the beginning of a line. One or more cradles carrying their paper rolls may be attached one behind the other along the bar 22, (Figs. 1 and 2), the bar being sufliciently long to enable additional cradles to be added if desired. Upon the removal of one or more of a series of cradles, the remainder may be adjusted along the bar to reduce the length of slack Web, caused by the travel of the carriage in letter-spacing direction. The rolls 8, 9, 10, (formed by webs wound on hollow tubes 9 are supported on the axles 20 between heads 25 having conical or tapering core sections 26, (through which the axle 20 extends) to enter the opposite ends of the tube or bore 9 of a roll, (see Fig. These cones aid in keeping the roll of paper nicely centered and away from contact with the standards, so that easy and-certain unrolling is eflected. This is very necessary in the caseof so sensitive a mechanism as a rapidly operated typewriting machine. The axle 20 is sufliciently long to support rolls of different lengths, the heads 25 beingadjustably held onthe axle by set screws 27 pass ing through hubs 28 on the heads. The axles 20 with their heads 25 and core sections 26 form spools for the rolls.

The distance between the standards of a cradle may be increased or. decreased to accommodate rolls of paper of different lengths, (bearing webs of different widths) by fitting the connecting rods 19 with detachable sections 19, at least one end of which rod being detachably secured to the adjacent standard. Referring to Figs. 1 and 2, the main sections 19 of the connecting rods are each rigidly secured at one end to one of the standards 16 of the cradle, the cradle being adjusted as to length by the addition of extension sections 19 to or their removal from the free end of said main section, fastening means, as screws 29, entering threaded sockets 30 in the outermost sections 19 of the rods, to connect them to the opposite standard of the cradle.

In Fig. 6, the main section 19 is releasably secured to the adjoining standard 16 by a threaded boss 19 passing through the standard and secured by a nut 31. In either construction, the sections 19 may be connected together and to the main section, by male and female threaded couplings, comprising bosses 19 and sockets 30, as shown in Fig. 6. The removable sections each have openings 32 into which a suitable tool may be inserted to release them from or secure them tightly to the adjacent sections.

The cradles are also adjustable as to breadth to accommodate rolls of different diameters, by mounting the opposite ends of the connecting rods 19 in cars 33 adj ustably connected to the respective standards 16, as by set screws 34 and slots 85. By loosening the set screws 34, the ears may be drawn out endwise in opposite directions to project substantially horizontally beyond and about in alinement with the ends of the standards, thereby moving the connecting rods 19 away from the bearings 21 of the axle and from each other, to accommodate rolls of larger diameter, the set screws 31- being tightened, when the rods have been sufficiently separated, to hold the ears where adjusted.

In Figs. 2 and 3, the extensible ears 33 are mounted onthe inner face of one standard and on the outer face of the oppositestandard (to afford ready access to the set screws 34 and to the fastening screws 29 when the latter are used) the ends of that standard having the ears on its outer face being recessed at 36 (Fig. 3) to afford clearance for the connecting rods 19 when the cradle is contracted to its minimum width.

Side guides or gages 37 for the opposite edges of the web or webs 11, 12 and 13 may be removably and adjustably secured to the guide bar 1 1, said gages, in the present instance, comprising disks 37 having hubs 88, the disks and hubs being slotted at 39 to be slipped onto or off from the guide bar transversely thereof, and held where adjusted by set screws 40.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
